Abstract

Ovaj rad opisuje postupak dobivanja normale površina objekta metodom fotometrijskog sterea. Dan je opis korištenog modela odbijanja svjetlosti nakon kojeg slijedi izračun normala iz više slika s različitim položajem svjetla. Objašnjeno je umjeravanje fotometrijskog stereo sustava i dan je kratak uvod u algoritme procjene dubine. Na kraju se uz diskusiju uspoređuju rezultati provedenog postupka za lokalni i globalni algoritam.

Abstract (english)

This thesis describes how to determine normals for an object's surface using photometric stereo. A description of used light reflection model is given, which is followed by calculation of surface normals from a set of pictures taken by varying light source position. Calibration of a photometric stereo system is explained and a short introduction on depth estimation algorithms is given. Lastly, there's a discussion and comparison of results for a local and global depth estimation algorithm.
